Culture methods of Dahlia

Before talking about the cultivation methods of dahlias, we need to tell the flower friends that the pot cultivation of dahlias is difficult and difficult to take care of, so if you are potted dahlias, you need to play a hundred and twenty thousand spirit to learn the maintenance methods of dahlias.

In order to make it easier for flower lovers to understand the culture methods of dahlias, this article will talk about the cultivation of dahlias according to different steps, so that they can master more knowledge about dahlias as much as possible.

1. Conservation of the environment

Whether potted or planted on the ground, they all need to be maintained in a sunny environment and to be leeward, because the stem of Dahlia is relatively weak, easy to break, can not stand the strong wind, and should be slightly shaded when the sun is more poisonous in summer. If long-term maintenance in the environment of lack of light, the root system is weak, the leaves are thin and the stems are thin, the flowers are small and light, and even cannot blossom.

2. Soil selection.

Because dahlias like to be wet and afraid of waterlogging, fat and excess, the soil should be fertile and loose (in fact, most flowers and plants require fertile and loose soil).

3. Planting

Dahlia is a tuber plant with huge tuberous roots. generally, what flower friends buy is tuber roots. Planting is actually very simple. Here you need to talk to Hua you about covering soil. Generally speaking, covering soil is about 3 centimeters. At the initial stage, it is less watered and drier. Wait for the bud and then water it step by step.

4. Watering

Although Dahlia likes wet but is afraid of waterlogging, it is also afraid of drought, and its roots are easy to rot if it is watered too much, but its leaves are large, grow luxuriantly, and need more water. If it is short of water and wilts, it can not replenish water in time, and after sunlight, the edges of the light leaves are scorched, and the heavy ones fall off, so the water permeability of the soil is very important, and it also needs flexible watering according to the soil moisture.

5. Fertilization

Once the dahlias bloom, they will continue to bloom, and the ones that bloom are getting smaller and smaller, and they need a lot of phosphorus and potassium fertilizer in the later stage, but dahlias are afraid of excessive fertilizer, so fertilization should be carried out in accordance with the principle of applying thin fertilizer and applying thin fertilizer every other week.

6. Maintenance measures of Dahlia in winter

(1) stop watering: stop watering immediately after the dahlias fade, forcing the stems of dahlias to go into dormancy.

(2) pruning thoroughly: when the stem of Dahlia is completely withered and yellow, cut off all the stems that are more than 6 cm above the ground. Prepare to enter the indoor storage.

(3) Storage conditions: the temperature in the storage room must be kept at 15 °C. And the storeroom must be dry and must not be watered during storage.

(4) Storage overwintering: it should also be noted that when digging up the root tuber, do not damage the root tuber as much as possible. If it is a potted plant, it is best not to take off the pot, wait until the pot soil is very dry and the outdoor temperature drops to 3 degrees Celsius, move people indoor to pile up for the winter.

If the winter temperature in the city is not suitable for the growth of dahlias, cut off the water and wither the leaves, dig up the root and plant it again in the following spring.

Culture methods and skills of Dahlia how to cultivate Dahlia

As one of the most widely cultivated ornamental flowers in the world, Dahlia has become a famous flower in the world. After being introduced to China, dahlias originating from Mexico have been domesticated and cultivated for a long time, and now there are many varieties, both in color and petal shape. With the widespread planting, dahlias are now very popular in China. Dahlias can not only be planted in flower beds, but also can be cultivated in potted plants at home.

It has strong adaptability and can grow well under the condition of high temperature in summer.

2. Soil: avoid sticky heavy soil, loose and fertile sandy loam. Fertile sandy loam is the best cultivated soil, and good drainage and sunshine are needed. Dahlia is suitable for loose sandy loam, rich in humus and good drainage. In the daily management, loosen the soil in time and eliminate waterlogging in the basin, because the fleshy root of Dahlia rotted when there was too much water content in the soil and poor air permeability.

3. Watering: potted plants avoid stagnant water, otherwise bulbs are easy to rot, reasonable watering and fertilization should be given during the growth period, and sufficient light should be given to make them grow healthily and bloom luxuriantly. It is watered once a day in summer and every 3-5 days in winter. Dahlia like water but avoid stagnant water, both afraid of waterlogging and drought, this is because the big flower is fleshy root, too much watering root is easy to rot.
